A tool that takes your upcoming Calendar entries and creates blog posts of the events

A code snippet that you can add to your website that enables visitors to your site to click on a link to comment on your content on their own blog

Code that allows you to search blogs on various topics, find entries, and again allow users to comment on their own blog

And finally, Blog.gears, an offline blog editor:

I tend to write a fair share of blog posts, and whenever I am writing them while offline I tend to open up Textmate to do the write-up. Wouldn’t it be nice if I could open up my blog editor and do it all while I am offline?

The architecture behind the editor follows the pattern of:

The UI looks to the local DB for data

When an event happens it gets queued

When an event happens the UI tries to send it to the cloud

Events have status flags to let the system know what is happening

We interviewed Pamela Fox about the application, and she went through the architecture at a high level, and also did a screencast of the application itself.

Interesting tool, I can see it’s uses for a blog engine. Though in general terms I must say I’m a bit skeptic to Gears, mainly because it reduces your server to a “data storage” and basically forces you to stuff lots of business logic on the client in the form of JavaScript…
I think it would probably be impossible for Gaia to utilize since all that’s rendered in a Gaia app is initiated by some event happening on the server and caching such things in a “cacher” (like Gears) would be impossible…
